Walking with dog in field unexpectedly containing sheep and lambs. 

See how the dog which has been trained, using an e-collar, to avoid going close to sheep on its own and so not to want to chase or attack them, stops and seeks guidance from the owner when it first sees the sheep and only advances when the owner is alongside and moving forward, The dog then stays close without command and actually moves to the side of the owner furthest away from the nearest sheep.
